I know there is no option for it now but why couldn't you get a Sprint phone # assigned to your Uconnect? It already has the cell service capability. Then it would not be dependant on a bluetooth connection to an external phone. Wonder why they didn't allow that in the design. Doesn't seem like a far reach.

They used to build phones into a lot of high end cars back in the 90's, but nobody used them much. Point is, we all carry an expensive smart phone in our pocket almost every waking moment of our lives, so why hard wire it into the car rather than just integrating into the one you have?

I don't think you would have to build or hardwire anything in. It already has Sprint cellular service, eg. Assist/911 calls, Data- Bing etc. That's why I think having a stand alone # would not be much of a stretch. And with most of the carriers allowing you to add a line for 10 bucks I think the option would be used. Some advantages would be no battery charging concern, if you forgot your phone you're still good, you could call your car if you stepped out and had passengers inside, etc.
